Abstract

The invention relates to a vehicle dragging device with a buffer function, which effectively solves the problem of no buffer function in the existing vehicle dragging device. The vehicle dragging device is characterized by comprising a box body, wherein a rope winding wheel is arranged in the box body; an elastic spring is arranged on the rope winding wheel; cylinders are arranged at the left sideand right side of the box body; a plurality of transverse rods are arranged in each cylinder; a first press spring is sheathed on each transverse rod; a circular pipe is arranged in each cylinder; ablocking disc is fixedly arranged on each circular pipe; press rods are uniformly distributed at the outer side of each blocking disc; a ratchet and paw structure is fixed on each press rod; a friction wheel is arranged in each ratchet; a threaded rod is arranged at the outer side of each friction wheel; each friction wheel is provided with internal threads which are matched with the threaded rod;a magnetic ball is fixed at the outer end of each circular pipe; a semispherical magnetic sleeve is arranged at the outer end of each ball, and is fixedly connected with a rope; the other end of therope is connected with the rope winding wheel; a second press spring is arranged at the part, in each circular pipe, of the rope. The vehicle dragging device has the advantages that the conception isnovel, the structure is skillful, and the practicality is high.

Description

technical field [0001] The invention relates to the field of trailer equipment, in particular to a trailer device with a buffer function. Background technique [0002] Cars have become an indispensable means of transportation in modern people's lives, but in life, it is inevitable that cars will run out of oil, or break down and break down. For emergency rescue, there are many types of tow trucks. There are professional tow trucks, which lift the car as a whole and transport it away. This kind of tow truck requires professional tow truck personnel and professional tow truck equipment, and the cost of tow trucks is high. In the face of general minor faults In the case of breaking down, still use a tow rope or a tow bar to tow the vehicle. [0003] The tow rope has the problems of being light, cheap, long towing distance, and easy to carry and install. However, because the tow rope is in flexible contact with the vehicle, it is easy for the vehicle behind to rear-end the vehi...
